IMPROVEMENT IN REVOLVING ATTACHMENTS FOR GAS-BURNERS.

Specification forming part of Letters Patent No. 137,406, dated April 1,1873 application filed February 20, 1873.

To all whom it may concern:

Be it known that I, JACKSON OGDEN BEL- KNAP, of Mobile, county ofMobile, State of Alabama, have invented a novel Improvement as anAttachment to GasOhandeliers, Street- Lamps, or other Lights, of whichthe following is a specification:

This invention has for its object the revolving of colored, transparent,semi-transparent, and opaque zones, pictures, 850., composed of stainedglass, gelatine board, isinglass, or diaphane, around a gas-light globeor lamp, by means of the ascending column of heat from said lightoperating upon or against a series of stationary and reversible fans,flags, and cones, attached to a vertical shaft inserted downward througha metal loop bearing and resting upon a metal or glass base, re-

volving by the means stated, and having connected with it, under thefan-wheel A, one or more reflectors of any desired form, which alsorevolves with the shaft. Upon the upper point of this shaft, and abovethe fan-wheel A, is another loop of metal, with hole in the top andplates, as the one before described, into which another shaft isinserted, having a series of cone-reflectors reversibly attached; also,reversible fans or flags, which serve to move the upper shaft in theopposite direction from the fan-wheel A. Connected with the shaft orbottom of the reflector, under the fanwheel A, are three or more armsconnecting with a single circle of metal, to which are attached a seriesof transparent zones of colors, composed of either stained glass,gelatine- ,board, or isinglass; also, opaque objects, photographs, andother pictures, all of which are both detachable and interchangeable, inorder to make variable appearances in this improvement.

The upper series of fans and reflectors also serve to revolvetransparent colors, pictures, &c., attached thereto, and which are alsodetachable and interchangeable, and move in a contrary direction to thefan-wheel A, both parts being in motion at the same time.

All the above-described parts are sustained by one or more supporters,E, which may be attached to a collar around the burner, or start fromthe upper edge of any gas-globe in any suitable manner, the shaftresting on a base below.

This invention is represented by four plates, as follows:

Figure 1 shows a view of one form of the improvement complete. Arepresents the fanwheel; B, the circle of reversible cone-reflectorswith reversible fans; E, the supporters; F, the transparent zones,pictures, ac; G, the arms; H, the single circle to connect the zones orpictures, and to which they are temporarily attached. I is thereflector.

Fig. 2 represents a seriesof fixed fans, marked A.

Fig. 3 shows a series of reversible cone-reflectors, B, with reversiblefans.

Fig. 4 shows the loop, plates, and screw D; also, the base of thereflector connected with the shaft 0, which is inserted point down,resting upon or in a glass plate supported by supporters E.

The devices of fan-wheels, wings, pivots, &c., are not new, nor do Iclaim them as such; but only desire to claim, in combination, such useof these parts as will produce the effects and results described in theforegoing.

This invention, as represented, has been described as applied to fixedgas-burners only but it is obvious that it is equally applicable tooil-lamps of every description; also, to portable and stationarysignal-lanterns and light-houses generally.

Claims.

What I claim as novel, and desire to secure by Letters Patent, is

1. A metallic frame, constructed substantially as shown, and adapted tohold pictures, colored plates, &c., said frame to be revolved around thelight by the heated air arising from the lamp or gas-jet acting upon thereversible fans or flags A and B, as shown and described.

2. The combination of a series of revolving fans or flags and cones,fixed and reversible, marked A B, connected with shaft 0, loop, metaland glass plates, and screw D, reflector I, arms G, circle H, zones orpictures F, with the use of stained glass, gelatine-board, isinglass,and diaphane, all of which are detachable and interchangeable, eachpart, as shown by the drawing, arranged one above the other, both ofwhich revolve in opposite directions at one and the same time,substantially as and for the purposes hereinbefore set forth.
